What is best way to replace Polybutylene water pipe?

I have polybutylene water piping leading from the water meter into my house. The pipe has become brittle and has started to leak. The three methods that various plumbers have told me about include: Trenchless re-piping. They run a cable through the pipe from the house to the meter and then pull new copper pipe through while pushing the old line out. Missle or mole - A remote control machine that is sent into the pipe from the meter, basically splits the old pipe as it drags the new pipe behind it. Digging a trench from the meter to the house, punch a hole through the wall anc connect to piping while capping where the service currently comes in. I would like to hear people's experiences related to any of the above methods as I am trying to figure out which approach would be best. I hear that the trenchless repipe isn't always successful (about 70% success rate) and they may have to dig up the yard anyway. BTW - It is too late for me to make a claim under the class action lawsuit against Company that made the pipe.

Depending on the type of soil you have I think that replacement with new pipe is the best way to go.

Welcome to the club. My polybutlyene pipe cracked just downstream of the meter and I had the pipe replaced with 1 inch copper the old fashioned way, all 200 feet of it. The plumber dug a trench with a small backhoe and removed the plastic and laid the new copper with brazed joints. The only way to fly.
